Numerical control radial revolving knife device

Abstract

The invention discloses a numerical radial revolving knife device. A servo motor is fixed to one side of the box. A ball screw and a ball screw nut are located in the box. One end of the ball screw is fixed to an output shaft of the servo motor, and the other free end of the ball screw goes deep into a hollow part of a sliding sleeve. The ball screw nut is fixed to one end of the sliding sleeve. A pull rod is fixed to the other end of the sliding sleeve through an adapter. A guiding key is fixed to the sliding sleeve, contact points of proximity switches stretches out of the guiding key, and the feed proximity switch and the retreat proximity switch are fixed to a protection sleeve arranged outside the sliding sleeve in a sleeving manner. A movable groove of the guiding key is formed in the inner hole wall of the protection sleeve. According to the numerical radial revolving knife device, knife feed is stable, the machining size of machined parts is adjusted at will and controlled through programming at will, and the size requirement can be accurately met. Machining of part channeling, end face finish turning and chamfering and machining of hook faces, special-shaped faces and other special faces can be achieved, and the application range is wide.

Description

technical field [0001] The invention relates to a numerically controlled radial long knife device, in particular to a numerically controlled radial long knife device capable of grooving parts, finishing end faces and chamfers, and processing curved surfaces and special-shaped surfaces. Background technique [0002] The commonly used radial long-knife mechanism is generally controlled by a hydraulic cylinder. The small diameter of the hydraulic cylinder and the high oil pressure lead to too fast feed speed, while the large bore and small oil pressure easily cause the hydraulic cylinder to crawl; that is, the hydraulic cylinder control directly expresses What comes out is that the feeding is unstable, the processing size is not accurate, and the processing range is small. For some special surfaces, such as curved surfaces and multi-boss special-shaped surfaces, only forming knives can be used for processing.
